The short answer: A 2026 Tesla Model Y Long Range AWD costs about $5.89 per 100 miles to charge at home in Maryland, and $19.24 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 21.40¢/kWh, up from 19.89¢/kWh in August 2025 and about 18% above the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $13.43 in a 30-mpg gas SUV at AAA’s Maryland average of $4.030 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

EV vs gas in Maryland: cost per 100 miles

Maryland’s regular gas averaged $4.030 a gallon on October 28, 2026, the 18th-cheapest among the 50 states and the District (AAA). Electricity in Maryland is the 15th-highest residential average among the 50 states and the District of Columbia.

Per-100-mile cost uses EPA combined ratings. The yearly column is the same rate times 12,000 miles, a round number chosen for comparison, not a measured average. Electricity is August 2026; gasoline is October 28, 2026.

Checked on the Model Y: 27.50 kWh/100 mi × $0.2140/kWh = 5.8850, which rounds to $5.89 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.030 = 13.4330, or $13.43. The break-even electricity price is $13.43 ÷ 27.50 kWh = 48.85¢ per kWh.

Utility EV rates in Maryland

The Alternative Fuels Data Center lists 2 utilities in Maryland with a residential EV time-of-use rate or managed-charging program: Baltimore Gas and Electric Company (BGE) and Delmarva Power. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.

Why it matters: the state average above blends every rate plan. An overnight EV rate is usually the cheapest power a utility sells, and the car can be scheduled to charge only in that window. Put the off-peak price from your tariff into the calculator to see the difference.

Public charging in Maryland

The AFDC counted 5,649 public charging ports at 1,694 locations in Maryland on October 28, 2026: 4,034 Level 2 and 1,603 DC fast, plus 12 Level 1. AFDC also counts about 120,500 battery-electric vehicles registered in Maryland through 2025 (2.4% of light-duty registrations). That is about 21.3 EVs per public port, against 21.7 nationally, the 14th-most EVs per port among the 50 states and the District. The two counts are from different dates, so treat the ratio as a rough measure of how busy public charging is.

Paren’s Q3 2026 report does not state a Maryland fast-charging average, so this page uses its U.S. average of $0.540 per kWh (off-peak $0.438, peak $0.637). Tesla Supercharger members averaged $0.396 and non-members $0.569 nationally.

Fast chargers usually bill the energy delivered to the car, which is less than the EPA wall figure. A rough estimate of delivered energy, the wall figure × 0.894 (mean Level 2 AC efficiency from Sears, Roberts, and Glitman, 2014, not a DC fast measurement), puts the Model Y at about $13.28 per 100 miles at $0.540/kWh. Per-minute billing and idle fees are not modeled.

Cost to charge five common EVs in Maryland

Home cost uses 21.40¢/kWh. A full charge is the EPA wall energy to drive the rated range from empty, not a usable-battery figure. Public DC is EPA wall energy × $0.540/kWh (Paren, U.S. average); a station that bills energy delivered to the car will charge somewhat less, one that bills by the minute may charge more.

FAQ: charging an EV in Maryland

How much does it cost to charge an EV at home in Maryland?

At the EIA August 2026 average residential price of 21.40¢ per kWh, a 2026 Tesla Model Y Long Range AWD costs about $5.89 per 100 miles and $19.24 for the wall energy to drive its 327-mile EPA range. Across the five EVs on this page the home cost is $5.20 to $6.73 per 100 miles. EPA consumption is measured at the wall, so charging losses are already included.

Is charging an EV cheaper than buying gas in Maryland?

At home, yes, against a gas SUV. With AAA’s Maryland average of $4.030 a gallon for regular on October 28, 2026, a 2026 Honda CR-V FWD (30 mpg EPA combined) costs about $13.43 per 100 miles, versus $5.89 for the Model Y charged at the August 2026 residential average. A 2026 Toyota RAV4 hybrid (43 mpg) costs about $9.37, so home charging is also cheaper than that hybrid in Maryland. Home charging stays cheaper than the gas SUV until electricity reaches about 48.85¢ per kWh.

Is public DC fast charging more expensive than gas in Maryland?

For the Model Y at Paren’s Q3 2026 U.S. average of $0.540 per kWh, 100 miles of EPA wall energy costs about $14.85. That is more than the $13.43 the gas SUV spends on the same miles at the AAA average, and $8.96 more than charging at home. Prices at a given station vary, and some stations bill by the minute.

Do Maryland utilities offer EV charging rates?

The Alternative Fuels Data Center lists 2 utilities in Maryland with a residential EV time-of-use rate or managed-charging program: Baltimore Gas and Electric Company (BGE) and Delmarva Power. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.

How many public EV chargers are there in Maryland?

The AFDC station count for October 28, 2026 shows 1,694 public charging locations in Maryland with 5,649 ports: 4,034 Level 2 and 1,603 DC fast, plus 12 Level 1. AFDC counts about 120,500 battery-electric vehicles registered there through 2025, or about 21.3 EVs per public port.

Is 21.40¢ per kWh the rate on my Maryland electric bill?

No. It is the statewide average residential retail price for August 2026 from EIA Table 5.6.A, and EIA marks 2026 values as preliminary. A time-of-use period, rider, tax, or fixed fee can move your all-in price. Open the VoltEdge charging-cost calculator and replace the prefilled average with the energy rate on your bill.
